This invention relates to an improvement in -gas burners. I

The object of the invention is to provide an improved gas burner which will more readily 6 effect a combustion oi. the gas at the outlet thereof from the burner. To accomplish this, flames are created which heat the inner wall of a shield and afford a means of heating air which arises and passes toward the point of the flame. Two heated air currents are created onopposite sides of the shield which strike the gas arising from. the gas burner at difl'erent angles and afford a mixture oil gas and air before the gas reaches the point oi. flame thus pre-heating the gas. Oril5 fices are provided at dlfierent angles in the sides of the gas burner, communicating with the gas outlet thereof, the lowermost passages creating small gas flames at the sides of the burner to preheat the passages of air both inside and outside the shield and additional passages are provided near the top of the burner to permit the thus heated air to flow into the main gas orifice and pre-heat the gas at a point below the point of combustion.

In the accompanying drawings: Fig. 1 is a top plan view of a gas burner showing my improvements applied.

Fig. 2 is a longitudinal sectional view there- W-through. J Fig. 3 is a slightly enlarged transverse sectional view through the burner.

Fig. 4 is a detailed sectional view through the main air inlet of the burner.

Fig. .5 is a detailed sectional view of a portion of a. burner showing a slot instead or main ori flees for the-discharge of the gas.

Fig. 6 is a top plan view partly in section showing the invention appliedto a round burner; and

Fig. 7 is a side elevation thereof partly in section.

Reterring to the form of burner shown in Figs. 1, 2 and 3, the bodyportion thereof 1 is tubular in shape and is-provided with: supporting legs 2. The body portion 1 is provided with a neck 3 which in the form shown in Figs. 2 and 3 has a series of vertical orifices 4, 'extendlng upwardly Passage-ways 5 extend at oblique angles of approximately 45". 1

Arranged along the opposite sides of the neck 3 at points above the passage-ways 5 are openings 6 from which horizontalair passage-ways 7 and oblique passage-ways 8 extend, these being divided by baflies 9 so as to create two currents of air leading inward through each of the openings 6. p

These air passage-ways 7 and 8 communicate at their inner ends with the main gas orifices 4 near their upper ends so as to direct heated air into the gas streams at points below the points of combustion.

A shield 10 fits over the upper portion of the gas burner enclosing theneck 3 and sides of the body portion 1 as shown in Fig. 3.. The shield 10 rests upon flanges 11 at the ends of the burner which hold it spaced from the sides of the neck and body portion, forming air channels 13 extending upwardly beside the neck and body portion and on the inside of the shield 10, communicating with the gas passage-ways 5 and the openings 6 A slot 14 is formed in the top ofthe shield 10 above the oriflces 4 to permit combustion at the top of the burner.

The designof the burner is such that flamesare created at the outer ends of the gas passageways 5 which heat the inner wall of the shield 10 and afford a means of heating the air which arises and passes toward the point of the flame. The openings 6 which communicate with the air channels 13 and have two air passage-ways 7 and 8 leading in from each of these openings 6 to the main gas oriflce 4, are designed to create air currents leading to the'gas arising from the tubular body portion toward the top of the burner and at different angles to afford a mixture of gas and heated air below the point of combustion which pre-heats the gas and facilitates ready combustion thereof. At the top of the neck 3 and along the sides of the neck the air channels 13- direct the air currents arising between the shield and the burner into the flameand gas orifices affording an additional source of air or combustion. These hot air currents are auxiliary to the normal cold air whichenters the gas in the body portion of the burner.

The body portion 1 has an air inlet nozzle 15 connected therewith and provided with a flaring flange 16 for directing air intothe nozzle 15 through slots 1'7 formed in the sides thereof. The outer end of the nozzle 15 is externally screw threaded seat 18 and receives an air regulator 11 iice to the sides of the body portion, and a shield extending over at least a portion of the body por-. tion and spaced therefrom for directing heated air upwardly from the regions oi the gas passage-ways to the region of the point of combustion.

8. A gas burner comprising a tubular body portion having a neck attached thereto, said neck having one or more gas orifices extending outwardly therethrough from the tubular body portion and having laterally directed gas passageways extending from each orifice to the sides of the neck, and a shield extending about the neck v 3 and spaced therefrom and arranged to direct heated air from the regions of the ends of the gas passage-ways approximately to the outer end of each gas orifice.

9. A gas burner comprising a tubular body portion arranged in annular form and having WILLIAM LOUIS HAGER.
